The short answer is that the Vredefort crater is the largest verified asteroid crater in the world. However, the Wilkes Land crater may be larger but it has not been verified, yet. The Vredefort crater was approximately 186 miles (300 km) in diameter, 3 miles (5 km) deep, and around 2 billion years old. It is located in South Africa’s Free
What is the biggest crater on Earth? The Vredefort crater, with an estimated diameter of 300 kilometres, is the world’s largest known impact structure. It was created when an asteroid measuring at least 10 kilometres landed on Earth an estimated 2 billion years ago.
An excellent example of a crater produced by this type of impact is the geologically young (50,000 year old) Meteor Crater in northern Arizona. This crater is 1.25 kilometers (4,100 feet) across, 170 meters (560 feet) deep (that of an approximately 60 story building), and has a circumference of nearly 5 kilometers (over 3 miles). The Cretaceous–Paleogene ( K–Pg) extinction event, [a] also known as the Cretaceous–Tertiary (K–T) extinction, [b] was a sudden mass extinction of three-quarters of the plant and animal species on Earth, [2] [3] approximately 66 million years ago. The event caused the extinction of all non-avian dinosaurs. . 840 523 923 161 480 524 734 445
